SIEEGIFIGATION forming part of Letters Patent No. 686,448, dated November 12, 1901. Application filed August 8, 1900. Serial No. 25,737. (No model.)

To all whom it may concern.-

Improvements in Brush-Machines5 and I do. declare the following to be a full, clear, and.

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refthereon, which form apart of this specification.

This in vention relates to a machine for malt-1 ing brushes; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide simple and efficient means for conveying the stock in tufts into the path of a reciprocatory plunger, whereby said stock is forced into cells in the brush-block, to provide means for forming and feeding the staples to the tufts of stock on the carriage, so that the operation of forcing the stock into the brush-block carries therewith the staples which confine the stock within said block, and to provide means for moving the carriage or stoek-conveyer and driving the other operative parts of the machine in conjunction therewith to inake'perfect and complete the machines operation.

The above object is attainedby the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a machine embodying my invention. Fig. 2 is a side elevation thereof, parts of the frame being broken away. Fig. 3 is a vertical section as on line 3 3 of Fig. 2. Fig. 4 is a detail in'elevation of the Wire-feeding and staple-forming mechanism. Fig. 5 is a vertical section in detail through a portion of the staple-forming mechanism and the mechanism for feeding the staples to the tufts of the stock on the carriage. Fig. 6 is a horizontal section as on line 6 6 of Fig. 1, the wire-feeding mechanism appearing in plan view. Fig. 7 is a plan view Fig.

erence being had to the accompanying draw-- lugs, and the figures of reference marked v S is a longitudinal sectional view as on line 8 8 of Fig. 7. Fig. 9 is a transverse section as on line 9 9 of Fig. 7. Fig. 10 is an enlarged detail in sect-i0u,showing the position of parts at the time of the descent of the plunger in the operation of forcing a tuft of stock through Fig. 11 is a horizontal section through the guidingtube as on line ll 11 of Fig. 10. Fig. 12 is a detail in section, showing a tuft of stock forced into a cell in the brush-block by the reciprocatory plunger.

Referring to the charactersof reference, 1 designates the supporting-frame carrying a bed or table 2.

the driving-shafts and operative mechanism. Projecting from the face of the standard 3, near the base thereof, is a horizontal bracket 5, which is split longitudinally from its outer end, as shown at 6 in Fig. 11. Said bracket supports upon its outer end a horizontal guide 7, adapted to receive and direct the endless tuft-conveyer, said conveyer comprising a series of pivoted links 8, having beveled sides 9, which engage in an undercut way in said guide 7, whereby said conveyer is directed in its movement. Mounted between the divided members ofthe bracket 5, at the outer end thereof, is a vertical guiding-tube 10, which is composed of two semicylindrical parts clamped between the sides of the bracket 5 by the transverse bolts 11. This tube is so positioned that the aperture 12 therethrough will register with the way in the guide 7 and with the aperture 13 in the links 8 when said links are brought into alinement therewith. Said con veyer is,in effect, an endless sprocketchain, comprising the links 8,pivotally united by the blocks 14. Said chain or conveyer passes around the sprocket-wheels 15, 16, and 17,- respectively, which are mounted upon suitable shafts journaled in the frame and which are arranged in a triangle, as clearly shown in Fig. 1, motion being imparted to said conveyer through the medium of the shafts 18 and 19 of the sprocket-wheels and 17, as hereinafter explained. v

The table upon which the brush-block 20 is supported comprises a small circular disk 21, having a depending bracket 22, adapted to be clamped by a transverse bolt 23 between I Mounted upon said table are standards 3 and 4, respectively, which carry the sides of the bifurcated upper end 24 of a stem 25, embraced by a split sleeve 26, which is in turn clamped upon asupporting-rod 27, so as to enable said sleeve to be swung and adjusted vertically. Bolts 28,passing through the projecting lips 29 of said sleeve, enable it to be clamped upon the stem or standard of the table 21. The lower end of the standard of the table is engaged within the sleeve by a hand-screw 30, whereby by turning said screw the table 21 may be raised and lowered. The hand-screw 30 is locked by a jam-nut 31 when properly adjusted. The manner of mounting the table on the upper end of the standard 25 allows of the tilting of said table, while the adjustable sleeve 26 and the movement vertically of the standard within said sleeve enable said table to be adjusted to any desired position or angle, so as to place the blocks in proper relation to the lower end of the guiding-tube 10, which depends directly over said table. It will be seen that the lower end of the guiding-tube is slotted, as at 32, the purpose of which is to permit the folded ends of the tuft 33 of the bristles to pass therefrom after said tuft has been secured in the brush-block. To provide for varyinglengths of tufts, pins 34 may be passed across the slotted opening 32 of the guiding-tube to prevent a too early escape of the tufts from the tube, as might result where a short length of stock is used, and prevent a proper entry of the stock into the cells of the brush-block.

The reciprocatory plunger 35 is adapted to engage the tuft of stock upon the conveyer and carry it downward through the tube 10 into a cell of the brush-block. To confine the stock in place and direct said plunger in its movement, the links 8 of the chain or conveyer are provided with a short post 36, standing vertically from opposite ends of each link on opposite sides of said central opening 13 therethrough. Between these posts the tufts of stock are confined and extend transversely of the conveyer. Said posts stand approximately parallel and form between their opposed faces a way 37, (see Figs. 7 and 8,) down which said plunger and stock are directed to the opening 13 through said link, through which opening they pass into the directing-tube 10 and thence into a cell in the brush-block, as illustrated in Fig. 12. To prevent a possible springing of said plunger and to direct it perfectly in its operation, its opposite sides are provided with vertical flanges 38, which project laterally therefrom and which 'enter the channels 39, formed in the opposite vertical faces of the posts 36, whereby said plunger is directed in its movement. Said plunger is mounted in the lower end of a vertical shaft 40, supported in suitable guides 41 and receiving motion from a rotary disk 42, carrying a pin 43, which engages in a slotted head 44, carried by said shaft, whereby a reciprocatory movement is imparted to said shaft and to said plunger by a rotation of said disk.

The disk 42 is mounted on a counter-shaft 45, which is driven through the medium of a gear-wheel 46 thereon, which meshes with a pinion 47 on the main shaft 48, carrying the driving-pulley 49.

The endless chain or conveyer is driven through a rotation of the shafts 18 and 19, carrying the sprocket-wheels over which said conveyerpasses. Anintermittentmovement is imparted to said shafts by means of a reciprocatory bar 49, (see Fig. 3,) having slots at its opposite ends, through which said shafts pass, respectively, and provided at each end with a pawl 50, adapted to engage with the respective ratchet-wheels 51 on said shafts. Attached to the center of said bar is a lever 52, which is fulcrumed upon the shaft 48 and provided at its upper end with a fork 53, which embraces a cam 54 upon the shaft 45, whereby a rotation of the shaft will oscillate the lever 52 and impart a reciprocatory movement to the bar 49, causing the pawls carried by said bar to engage their respective ratchet-wheels and turn the shafts 18 and 19 intermittently, as will be well understood.

\Vith the operation of forcing the tufts of stock into the brush-block a staple 55 is carried downward by the descent of the plunger 35 and driven into said block to secure the tuft of stock therein, the sides of the staple engaging in the channels 56 in the opposite walls of the tube 10, which register with the channels 39 in said posts and receive the flanges 38 on said plunger, whereby the staple is directed perfectly into place.

The staples which are employed to secure the tufts of fiber in the brushblock are formed of a continuous strand of wire 57, which is carried into the machine between the feed-rollers 58. After passing between the feed-rollers the wire is directed through a guide 59, which is apertured to receive it and which terminates in a beveled block or die 60, from which the wire protrudes. The wire from which each staple is formed is severed from the strand by means of a shearplate 61, which is mounted upon the vertically-reciprocatory slide 62 and which upon its descent carries said shear-plate past the beveled face of the die and cuts from the strand the desired length of wire to form the staple. The severed strand of wire from which the staple is formed lies across the upper edge of the narrow plate 63 and is bent into shape by the descent of the opposed forming-blocks 64, also mounted upon the slide 62, and which bend the severed strand of wire over the plate 63 and shape it in the form of a staple. After the staple is formed it is discharged onto the inclined chute 65 by means of the beveled plates 66, which are also located upon the slide 62 above the formingblocks 64 and which by a further descent of the slide force the staple onto the inclined chute 65, down which it passes to the way 67 in the guide 68, with which said chute communicates. The staple is prevented from dropping from the way in said guide 68 by means of a spring 69, mounted on the face of: said guide, whose free end curves into an aperture in the guide and engages the staple 55 in the way therein, whereby said staple is arrested and suspended Within said way adjacent to the discharge end thereof. Adapts ed to reciprocate vertically'in the way of said guide 68 is a plunger 71, whose upper end is attached to the head 44 of the shaft of the plunger 35, whereby said pl'ungers 35 and 71 are caused to reciprocate in unison. The descent of the plunger 71 carries thestaple from the way in the guide downward astride of a tuft of stock which at the time of said operation occupies a position in the carrier directly below said plunger, so that at each operation of said plunger 71 a staple is depositedastride of a tuft of stock in the carrier in position to be carried with the stock downward. through the guiding-tube 10 and into the brush-block by the operation of the plunger 35 when said stock is brought into the path thereof by the movement of the carriage.

The result of the operation above described, is that the staples are formed and successively presented to the stock on the moving carriage or conveyer in position to be forced with the stock into the brush-block by'a se-' rics of operations entirely automatic.

Movement is imparted to the slide 62 by means of a camway 72 in the inner face of the rotary disk-42. Said camway receives a pin 73, (see dotted lines in Fig. 3,) projecting from a lever 74, which is pivoted at 75 to the frame and at its opposite end is provided with a slot 76, which receives a pin 77, projecting from the slide62, whereby a rotation of said disk 42 imparts a reciprocatory movement to said slide.

Motion is imparted to the feed-rollers by means of a bracket 78, attached to the bottom of the slide 62 and pivoted at one end to a link or connecting-rod 79, the other end of said rod carrying apin 80, which engages in' a slotted opening 81 in the outer end of the arm 82, which is mounted upon the shaft 83 of the lower feed-roller and carries a springpawl 84, adapted to engage a ratchet-wheel 85 on said shaft, whereby the vertical movement of the slide 62 imparts an intermittent rotation to said shaft of the feed-roller. order to cause the feed-rollers to turn in unison, the shaft 86 of the upper roller is geared to the shaft 83 of the lower roller by the gears 87 and 88.

In the operation of the machine the tufts of stock are fed to the traveling carriage or constaple-discharging plunger 71 the stock is in shape to perfectly receive the staple and is held from springing out of place. The continuation of the operation of the machine carries the tufts of stock, with the staples astride thereof, into the path of the plungers 35,which force said stock and staples into the brushblock, as before described.

The several operative parts of the machine are so timed that the carriage is at rest during the descent of the vplungers 3'5 and 71 and is moved a distance of one link when said plungers have received the highest point in a reciprocatory movement. The wire-feeding mechanism from which the staples are formed is also operated when the slide 62 has attained its highest point and before the descent thereof. The slot 81 in the lever 82 enables the throw of said lever to be regulated, so

as to control the length of the wire fed into the staple-former by each operation of said lever.
